86904913 ÷ 381 
We're looking to find how many times 381 goes into 86904913.

Advancing to step 1:
381 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 381

Moving on to step 2:
The number 381 fits into 86 0 times, leaving a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Include the next digit (9) from the dividend after 86, then repeat: 869 / 381

Going ahead to step 3:
If we divide 869 by 381, we get 2 and a remainder of 107.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 762 from 869 and we're left with 107.
Bring next digit (0) of the dividend behind the 107 and repeat the process: 1070 / 381

On to step 4:
381 goes into 1070 2 times with a remainder of 308.
Put 2 as the next digit of the answer. 
Result so far: 22.0
The remainder is 308 after subtracting 762 from 1070.
Take the next digit (4) from the dividend and append it to 308, then repeat: 3084 / 381

Advancing to step 5:
If we divide 3084 by 381, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 228.0
The remainder is 36 after subtracting 3048 from 3084.
Grab the next digit (9) from the dividend, add it to 36, then carry on: 369 / 381

Moving on to step 6:
381 can be fit into 369 0 times, resulting in a remainder of 369.
The number 0 becomes the next digit in our result. 
Result so far: 2280.0
If we take 0 away from 369, we end up with 369.
Bring next digit (1) of the dividend behind the 369 and repeat the process: 3691 / 381

Let's proceed to step 7:
When dividing 3691 by 381, we get 9 with a remainder of 262.
The next digit of our result is 9. 
Result so far: 22809.0
Subtracting 3429 from 3691 leaves us with 262.
Take the next digit (3) from the dividend and append it to 262, then repeat: 2623 / 381

On to step 8:
2623 divided by 381 is 6 with a remainder of 337.
The number 6 becomes the next digit in our result. 
Result so far: 228096.0
If we subtract 2286 from 2623, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 9:
381 goes into 3370 8 times with a remainder of 322.
Record the quotient 8 as the next digit in the result. 
Result so far: 228096.8
Subtract 3048 from 3370 to get 322.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3220, and continue the process.

Moving on to step 10:
The number 381 fits into 3220 8 times, leaving a remainder of 172.
Write down 8 as next digit of the result. 
Result so far: 228096.88
Deduct 3048 from 3220 and we're left with 172.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1720, and continue the process.

The quotient of the division is 228096.88, and the remainder is 0.172.
